9 kinds of vision

This is an extension for Inkscape which simulates 9 different types of vision. Again it's a color effect and therefore it can be found over at Effects->Color->Color Blindness after installation.

Supported modes:

• normal trichromatic color vision
• protanopia red-green blindness (no red cones)
• deutanopia red-green blindness (no green cones)
• tritanopia blue-yellow blindness (no blue cones)
• typical achromatopsia (no cones; rod monochromat)
• protanomaly (anomalous red cones)
• deutanomaly (anomalous green cones)
• tritanomaly (anomalous blue cones)

There shall be structure

Benefits

Hierarchical structures are always rather hard to explain with words alone. You've to identify the key items and then lay out their relation to each other - two at a time. This can take a couple of sentences and you'll also have to carefully check if everything is at the right place.

But it doesn't stop there. The worst part is probably that every user will have to parse your explanation very carefully. Of course that only adds a few seconds to the whole process, but those seconds accumulate. Your thousands (or even millions) of users might have done something more important during that time. They could have picked their nose for example, which is an activity many people enjoy more than reading documentation.

Yes, it's true. Reading documentation is really that exciting. So, we really should try everything possible to make it as quick and pain free as possible.
